Reaction Steps

0.25 g (0.94 mmol) of [2-methyl-6-(4-trifluoromethyl-phenyl)-pyridin-3-yl]-methanol (example 1M]), 0.15 g (1.03 mmol) of phthalimide and 0.32 g (1.20 mmol) of triphenylphosphine were dissolved in 10 ml of THF. The stirred reaction mixture was cooled down to 0° C. and a solution of 0.27 g (1.15 mmol) of di-tert.-butyl azodicarboxylate in 2 ml of THF was added drop by drop. Then, the reaction was warmed up to ambient temperature. After 1 hour, the solvent was evaporated and the residue purified by crystallization from MeCl2 and n-heptane to give 0.32 g of the title compound as a colorless solid.
